A beautiful cave about 1km southeast of Pálvölgy and Mátyáshegy Caves, and the most accessible of the three. The temperature at Szemlőhegy is 12°C and the cave has no stalactites or stalagmites; instead, it's notable for its peculiar grapelike formations. The tour lasts 35 to 45 minutes. The lower part of the cave is used as a respiratory sanatorium due the exceptional quality of its air.
